I only reserve full price spending every once in a while for games I'm particualrly excited for, which doesn't happen often. These include GTA V, Skyrim, and The Witcher 3. Most games I can wait for a price I feel is reasonable for me (around £20 usually)
Hmm, your 2gb vram may only really allow middle graphics at best I'd say. I'm gonna be playing on a 780ti (3gb) and I'm not expecting to be able to max this thing 60fps. Honestly though, I'd say you'll still get a fairly fine looking game with those specs, just don't expect to reach the upper tiers of graphic settings.
